The mobile phone of the eyewitness, who had recorded the final moments of the Mi-17 chopper before it crashed in Tamil Nadu's Coonoor, has been sent for forensic examination.
The Indian Air Force (IAF) chopper that crashed on December 8 resulted in the deaths of Chief of Defence Staff (CDS) General Bipin Rawat, his wife Madhulika and 11 armed forces personnel.
The lone survivor of the crash, Group Captain Varun Singh, is still critical and is undergoing treatment at the Bengaluru-based military hospital.
